When asked if he was confident about the repair, Allison said: “Yes,”
although he admitted that the car was now 1kg heavier.
“We’re only talking about 1kg, which is manageable,” he said. “It won’t
have any significant impact on handling or performance.”
Speaking about the problem, he added: “We arrived in Barcelona with a
brand new chassis, the E20-02. We completed installation laps on Tuesday
morning then Romain [Grosjean] left the pits for his first run of the day.
“As soon as he touched the brakes before turn one on his first flying
lap, he felt that something was wrong. He told us on the radio that he was
aborting that run and returning straight to the pits.
“We saw immediately that we had a problem with the mounting of the upper
front wishbone rear arm.”
The chassis will not need to undergo another FIA crash test, Allison said.
